Decoded

Reports string reverse current, reverse polarity; look at PV array, PV input terminal; confirm with string polarity measurement; do: string polarity correction, DC wiring check.

What can be behind String reverse current

Failure modes that present as the reported condition, and the tests that tell them apart.

What can be behind Reverse polarity

Failure modes that present as the reported condition, and the tests that tell them apart.
